.foi" deflating pneumatic tires, or removing valve members used in conjunction therewith- As is well known a valve for tires g'en'era'lly, comprises a threaded stein in which is seated avalve core whiclnincludes a slender valve sprin actuated rod and with this stem is provided a valve cap- My in mention is designed as an attachment for these caps, it being understood, however, that the cap is provided with a stem which constitutes a core remover.

Caps of t e general type of construction embodying core removing means are diificult to. operate, or morestrictly speaking, the removing operation is performed with much inconvenience due to the tendency of the cap to slip, from the iineers when changing thegrip during rotation hi this member or cap.

Again when it is desired to merely deflate a tire, one generally has to hunt for a slender article to insert into the valve stem for depressing the valve and such article must be held until the deflating operation is completed. It is to overcome these disadvantages that invention has been designed as a complete, article which may readily be used both to remove the core, being held in positiono'n the stern during such operation, and for deflating purposes, when it'is selfsustaining, the article constituting in addition a cap for the valve stem.

To this end the invention consists in the construction, combination and arrangement of parts all as hereinafter more fully de scribed, claimed and illustrated in these companying drawing, wherein:

Figure 1 is a side elevation of a pneumatic tire valve having my invention applied thereto.

This cap or body. is formed with a stem 6 project ing centrally therelrorn and this stemis notched at extremity strictly sp .ng is grooved tra ..versely as indicated at 6 eo-that it will straddle the upper end of the valve member 2 which, customary, has opposing nibs '7 adapted to he received in the transverse groove just referred to. The stem extension. furthermore, is provided with solid portion 8 directly adjacent to the not e '*v and. in the use of the as a a this solid portion impinges the i .lve rod 3 which is depressed when the extension r") is moved into the entrance of the valve stem. The valve 5 has attached thereto in any desired manner gripping means which consists of a cylindrical shaped body 9, the material which is preferably of resilient character. This body furthermore is formed with ascries of yieldable fingers 10 that surround the cap stem 6 in spaced relation thereto. The gripping means just described may be soldered to t s can so as to hold it in fixed rel tion the eto, and the body of the grip- 7 neans 1s iretcrably split longitudinally s indicated at 11 so as to enable it to positioned about the cap.

in Fig. l have shown the gripping means as a unitary ttachnicnt which may be provided as an article of manufacture itself susceptible of being sold to the trade as such for attachment to valve caps of the general type described above.

it will be noted that the body portion of the form shown iniFigsA is split longitudinally andthematerial being resilient The numeral 5 designates a the gripping means may readily be sprung open suflicient to permit of the attachment to the valve cap. Valve caps of this-type are usually provided with a centrally and coactionvof this portion with the walls'of the gripping means eflectively holds the latter against movement when the article is used as a core remover. A groove 12 is preferably spun in the body of the gripping means which assists in positionin the member upon the valve cap.

T)escribing the use of the invention, when it isdesired to deflate a tire the body of the vice is pushed on to the threaded extremity sufliciently far to enable thev notched eX- tremity of the stem 6 to straddle the nibs 7 on the valve. By rotating the device in the usual manner the valve will be unscrewed from its position and during such unscrewing the gripping fingers 10 eflectively hold the device in place whenever it becomes necessary for the operator to release the cap for the purpose of to continue the rotating operation.

It will be quite obvious that an article of this character possesses a distinct advantage byreason of the fact that one alknurled portion' threaded portion thereof The provide stem gripping fingers.

of' yieldable fingers ,being slightly flanged getting a renewed hold:

ways has at hand a ready means for deflating the tire or removing a valve whenever he has a valve cap for the stem, provided with the meansv for holding it in operative positions shown in the drawin ,hereto at-. tached. As an article 'of manu acture, fur-r. thermore, the gripping means may be easilyand cheaply manufactured for ready attachment to the conventional valve cap of the general type involving the core removing means.

Having thus described my invention, what I claim as new is 1. As a new article of manufacture. an attachment for valve stem caps comprising a sheet of resilient material rolled into an open-sided sleeve of substantially the same diameter as a cap and adapted to be sprung open constituting holding means therefor during rotation of the cap when removing a valve. said sleeve being slit a plurality of times and the slitted I In a device of the class described, the combination with a valve stem cap, a sleeve surrounding the same and having a series arranged to extend upwardly from the cap for rictional engagement with a valve stem Whenremoving a valve therefrom by means of the ca the at one and t ereof inwardly and also having a groove spun therein intermediate the length of the sleeve for holding the sleeve against relative displacement with respect to the cap.-
